BACKGROUND/OBJECTIVES Hospice care confers well‐documented benefits to patients and their families, but it is underutilized. One potential reason is inadequate family support to make end‐of‐life decisions and care for older adults on hospice at home. We assessed the association between amount of family support and hospice use among a population of decedents and among specific illness types. DESIGN Prospective cohort study using the National Health and Aging Trends Study waves 2011 to 2017, linked to Medicare claims data. SETTING Contiguous United States.
